SELF-DUMPING PADDLE-WHEEL.

Specification of Letters Iatent.

Patented Oct. 15, 1912.

To all whom it may concern..."

Be it known that I, Fnnnnaron J. Loon- WOOD, a citizen of the United States, and a resident of Newark, New Jersey, have invented a new and useful Self-Dumping Paddle-lVheel, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to embody the same in prac tice.

This invention relates to apparatus for commercially subjecting hides to the action of liquids, as for instance, to accomplish a washing thereof, but inasmuch as certain advantages characteristic of the same prominently appear in its more intense aspect as a paddle-wheel of the self-dumping type, it will be conducive to clearness to disclose the invention by way of a detailed description of such an embodiment thereof.

As typical of the applicability of this apparatus, it may be recalled that during the tanning process, hides are usually washed by being thrown at a suitable time into a socalled paddle-wheel z. 6., a vat of liquor in which rotates a wheel fashioned like an ordinary paddle-Wheel, and which rotates to keep the hides in constant movement inthe liquor and thus facilitate the action of such liquor on the hides. After a suitable period, the hides were fished out manually and substituted by others, either with or without a change of liquor. This operation was carried out at the expense of some little time and considerable trouble.

Now this invention has in contemplation the provision of an apparatus which, by reason of certain simple improvements, will enable the hides to be more readily replaced by others, and which will possess other advantages, such as greater facility in operation and the like.

of reference denote corresponding parts throughout the several views, of which:

Figure l is a side elevation showing in full lines the normal relation of the parts, and showing in dotted lines the position of the vessel when dumping. Fig. 2 is a plan view showing certain details not clearly exposed in Fig. 1.

The tilting vat constituting an element of my combination is shown more clearly by Fig. 1 and is indicated by the reference letter A. 1V bile this vessel may assume various shapes, it preferably conforms to that shown, in which gudgeons 39 and 40 upon which the wheel 1 and 2 indicate the ends and 3 and 4: are plates secured thereto and carrying gudgeous 5 and 6 located below and rearward of the center of gravity of the tilting structure. The bottom 7 of the vat may be curved (preferably concentric with the gudgeons as shown) and may be formed of suitable staves bound together by the iron straps 8, the ends of which pass through the pieces 9 and may be drawn tight by means of the nuts 10. The rear wall 11 may rise vertically to the upper longitudinal beam 12 which is secured to the side beams 13 and 14 by the iron plates 15 and 16. Tension rods or straps 17, provided with adjusting nuts, serve to draw the boards together and maintain the tightness required. The front wall 18 may be constructed in a similar manner, but preferably it slopes upwardly and outwardly to form a suitably shaped lip for discharging the contents when the vat is in the tilted position shown by the dotted lines.

The operating means for the tilting vat. may be exceedingly simple as indicated by B. Near the dumping edge of the vat are two right and left side eye-bolts :20 and 21 into each of which takes a hook such as that indicated by 22 at the end of the chain 23 suspended from the chain hoist 2 1, which may be carried by the rollers 25 riding on the track 26.

The pivotal support for the tilting vat is indicated generally by the letter C and may consist of a framework formed of the beams 28, 29, 30 and 31. The upper edge or beam 29 carries a pillow-block 32 in which is journalcd the gudgeon 5. This supporting frame is preferably so proportioned and arranged that the upper edge of the vessel will rise but little above the work-fioor 33, and thus enhance the general convenience of the apparatus.

The paddle-wheel is indicated generally by D and consists of two end pieces 34 and 35, to which are secured the blades 36 arranged radially as shown. Plates 37 and 38 are secured to the wheel ends and carry the gudgeons 3-9 and 40 upon which the wheel rotates. These gudgeons are journaled in the pillow blocks 41 and 42 which are in turn supported by the beams 13 and 14. It is to be noted that these pillow-blocks are arranged forwardly of the main pivots of the vessel, so that the center of gravity may be ofi' set. To enable the wheel to be driven, a gear wheel 43 is secured to one of the end pieces by means of the radial lugs 44.

The driving mechanism is referred to by the letter E and is very simple and may merely consist of the shaft-hanger 45 which supports a power-driven shaft 46 on which is a sliding pinion 47 adapted to be brought into mesh with the gear 43 when the latter is in the normal position. It will be perceived that the pinion, being set back somewhat to the rear of the center of the gear, will be automatically disengaged by the act of tilting the vessel.

It will thus be perceived that I have devised an apparatus whereby the several objects of my invention have been achieved in a simple yet efiective manner.

I claim 1. An apparatus for paddling hides combining a support, a vessel having an open top and pivoted at a lower axis to said support, a paddle-wheel journaled in an upper portion of said vessel and having its peripheral portion widely distant from the bottom and opposite sides of said vessel, a gear wheel co-axially secured to said paddlewheel, and a driving gear positioned above said gear and adapted to be disconnected therefrom when the vessel is tilted to dump the hides.

2. An apparatus of the nature disclosed combining, a support, a vessel having a discharge lip and pivoted to said support beloW and at one side of its center of gravity, :1 paddle-wheel mounted in the upper part of said vessel, and driving means for said paddle-wheel adapted to automatically disconnect therewith when said vessel is tilted.

3. An apparatus of the nature disclosed combining, a support, a vessel having an open top and pivoted to said support below its center of gravity, a paddle-wheel journaled on the upper edges of said vessel, a gear-wheel secured to said paddle-wheel, and a pinion carried by a driving-shaft and meshing with said gear at a point in its periphery rearward of its center.

In testimony thatI claim the foregoing as my invention, I have hereunto set my signature in the presence of the two subscribing witnesses.
